In December 2023, Christopher Whitehead from the Diocese of Clifton was appointed bishop-elect of the diocese,[1] replacing Bishop Mark O’Toole, who had been appointed as Archbishop of Cardiff a year prior.

On 1st February, the Catholic Bishops' Conference of England and Wales released a statement that Whitehead was under canonical investigation, and that the ordination would not take place, no reason was given.

The diocese covers the counties of Cornwall, Devon and Dorset, stretching from Penzance and the Isles of Scilly in the west, to parts of Bournemouth in the east.

It is divided into five deaneries: Cornwall, Dorset, Exeter, Plymouth, and Torbay.

The Centre promotes a wider "Grail community" to include non-resident women and families, and also publishes a translation of the Psalms.
